<p>1) Radio Environment models, 2) Mobility models and 3) Application/User Context models are utilized in a wireless communications network. Radio Environment models, implemented by a physical modeler (14) represent the physical aspects of the radio environment, such as shadowing losses, multi-path propagation, interference and noise levels, etc. Mobility models, implement by mobility modeler (16) represent users motion, in terms of geo-coordinates, obtained form geographic database (12) and or logical identifiers, such as street names, etc. as well as speed of user terminaletc. The context model, implemented by application context modeler (22), represents the present state and dynamics of each of these application processeswithin itself and between multiple application processes. These data are employed to optimize network performance.</p> |
